BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a shower product, and more particularly to a dual hand-held shower head assembly.

2. DESCRIPTION OF THE PRIOR ART

A conventional shower head assembly includes an overhead shower head and a hand-held shower head. The water outlet of the shower wall communicates with a water inlet end of a knob switch valve body through a water supply pipe. The knob switch valve body has two water outlet ends. The two water outlet ends are in communication with the overhead shower head and the hand-held shower head through water tubes, respectively. The user rotates the knob switch valve body for selecting the overhead shower head or the hand-held shower head to spray water. A suction cup assembly or a double-sided tape assembly is fixed to one side of the knob switch valve body. The suction cup assembly is sucked to the shower wall or the double-sided tape assembly is adhered to the shower wall for fixing the knob switch valve body. However, because the user needs to rotate the knob switch valve body for switching the overhead shower head or the hand-held shower head to spray water, the suction cup assembly or the double-sided tape assembly is easy to loosen, making it difficult to fix the knob switch valve body. The suction cup assembly or the double-sided tape assembly will slowly fail after a period of time. It is necessary to reinstall the suction cup assembly or replace the double-sided tape assembly frequently, resulting in high use costs.
